SPECIFICATION forming part of Letters Patent No. 291,210, dated January 1, 1884.

Application filed October 27, 1883. (No model.)

To all whom it may concern:

Be it known that I, PIERRE lVIAYRAND, of

the city and district of Montreal, in the Provthereby precluding any necessity of the operators going between the cars, and the accompanying risk of accident or possible injury. I attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of parts of two railway-cars connected by myimproved coupler. Fig. 2 is a plan view of the coupler in connection. Fig. 3 is a longitudinal mid-section drawn to a larger scale. Figs. 4 and 5 are face views of the two parts of the same. Fig. 6 is a part section of the car whose coupler carries the coupling-pin.

A and B are the draw-heads, the former carrying the link a, and the latter the coupling-pin b.

G is a shaft journaled in the frame-work of the car, and extending out past the sides of the same. On the ends of. this shaft, and overhanging the sides of the car, are the hand-wheels c c, by which the shaft 0 is rotated, and by which, also, as will be seen from the following, the coupling-pin may be raised when required. [I is a lifting-arm, fixed rigidly on the shaft by set-screws or in any other approved manner. It extends outward and up over the drawhead, where it is attached to the head of the coupling-pin.

a is a lifting-lever, also keyed to the shaft 0, and extends out past the end of the car, where it is attachedto the lower end of the lifting-rod e, which extends upward to thetop of the car in the case of a boxcar, thus bringing the control of the coupling-pin within reach of a person on the roof of the car. In passenger-cars the rod e may extend only to the top of the platformhand-rail, so thataper- I son on the platform can raise the pin without going between the ears. c is a guide for the coupling-pin when it is drawn up. Itis simply an upright case having an opening made in its front side, through which the connection of the coupling-pin b with the lifting-arm (Z passes. The guide may belifted out ofthe bed-pieceb', which holds it to the car-frame, when required. The pin is holdup bythe deviceshownin Fig. 5, which I will now describe. On the shaft 0 is fixed a lever, D, whose short arm is held up by a shoulder of the upper arm of the latchlever E, which is held against said short arm by the spring f. The other end of this spring is attached to the long arm of the lever D, which it throws up immediately the shoulder of the latch-lever above mentioned is withdrawn.

9 is a bar attached to the lower end of the latch-lever E, projecting out from the end of the car, and which, when pressed inward, disengages thelatch and allows'the spring f to throw down the pin 1). The rod 0 and its connection with the shaft 0 are common to both cars-the car whose draw-head carries the pin and the ever, the lifting-arm d is connected to the link a by the eyebolt h, instead of to a couplingpin, as in the other draw-head. By this arrangement the outer end of the link may be raised when necessary, so as to enter the coupler of an approaching car.

The car which carries the link also carries the coupling-arm t, which meets and presses against the bar 9 when the cars are brought together, and in the manner above described causes the coupling-pin to drop through the link as soon as it is in place in the draw-head.

What I claim as my invention is 1. In a railway-car coupler, the transverse shaft 0, having the hand-wheels co, the lifting arm cl, connected with the coupling-pin .b, the
